The Theme Font Changer disappeared from Tool Menu all of a sudden. I've been using it for years. It happened without me doing anything .Just regularly working with TB.

I managed to downloaded it and it shows as an Add-on however it doesnt show on the Too Menu so I cant use it. Fonts as they are now are extremely small.

I tried to go back in time, download again TB, deleete and reinstall Theme Font Changer but no success.

Are you using THIS link https://addons.mozilla.org/en-US/firefox/addon/theme-font-size-changer-for-tb/ ?

If that does not work, install a modified version that does not expire from http://www.rossde.com/ThemeFontSizeChangerNoexpire/index.html

right+click the "Get It Here" link, and use "Save link as" to save the XPI file to disk. Then in Thunderbird, at Tools > Add-ons, click the gear and pick "Install add-on from file"

The response above leads to the "rossde.com" site which says it is corrupt. Why can't Firefox make the figging menu larger?
